To all whom z'tmay concern:

, Be it known that I, CHARLESF, ANDERSON, of Charlestown, inthe county ot' Sullivanl and State of New'Hampshire, have invented a new and Improved Seeding-lvlachine; and I do hereby declare that the following is a.full,`

.clear,vand exact description offthe same, reference being'had to the annexed drawings, making a part of this specification, in which--` Y A Figure l is a side-sectional elevation ot' my improvement, taken in theline am, Fig.3. Fig. 2 is alsoal vertical section of the same, taken in the line y y, Fig. Fig. 3 is a plan or top view of the same. Fig. 4 is a front view of the same. Fig. 5 is a detached vertical section of one of the bearings of the shaft` which coinmunicatesmotion from thedriving-wheel to th seedgsliaes.

lSimilar lettersof'rference indicate corresponding partsfin the several figures.

This invention relates to an improvement in ,that class ot' seeding-machines inwhich two distributing'. devices are combined for the purpose 0fdistributing different kinds of seeds with one and the same driving mechanism; and j l understand'and construct my invention, I will proceed to4 describe it. 1 4 ,A

A represents ,an axle, andBB are wheels which are placed loosely ou the'end's thereof.

C C are eccentrics, which are placed on the axle, one near each end, and are'secured thereon by jam-nutsa The eccentricsU C' are encompassed by straps D D, o ne Ito each, and these straps areattached .to 'the under side` ct' arectangular frame, E,Which carries two seed;v boxes, F G, and also the mechanismby which the seed-slides areoprated. "The eccentric Uis provided with atlange, `1),.at each side, said anges being ot' double-cam vor oblique' shape, so'as to form shoulders'c, twoat each side of the eccentric .and at opposite poi'nts of its circumference.

' i is a slide-rod, fitted invsuitable bearings.

at the under side of the frame E, and operated by a lever, Il 0n the rod H two pendants, d `d, are placed, a pendant being at'each side of the eccentric (l, andfon the outer end of the rod H Aa pendent fork, e, is fitted, said ,forkI encompassing a catch,f, which, when dashed,

engagesfbyadjusting the rod H,'the axle-A with the wheel B.

`1 On the inner end'of the hub ot' the whetB. asp'ur-wheel, J', is placed, and on the frame E, between the two seed-boxes F G and par- 'I allel' with them, a shaft, K, is placed.` One -end of this shaft is fitted in a bea-ring, h, at-

tached' to the frame E, andthe opposite end is ttediu a tube or collant, which is fitted Both in a bearing, j, attacheilto the frame. bearings [tj are titten ou vertical rods if't", at-

tached tothe `frame Efand the bearings'are' allowed to slide freely up and Vdown on said rods, and 'are .securedat any desired points by set-screws i. The tube or collar i is allowed 'to slide longitudinally to a certain extent in its bearing j, butis. prevented from turning therein by means of at'eather, 7o, which works in a groove, l, in the bearing. portion ot' the shaft Kthat is fitted within the tube or collar t" has a zigzag groove made in y yit, as shownin Fig. 2. The portions mm of the groove are parallel with the shaft K; but

the portions 4t n are of'y spralpr 'screw -form, and communicate with thcportionsmmat opposite' endshso as to form afeontinuonsr groove. This will be clearly understood by referring to Fig'. 2. From the inner side ot' the tube-'or collare a pin, o, projects, said pin fitting in the zigzag' groove.-`

F '1 0 thelendot thel shaft K a pinion, L, is placed. This pinion Vhas its cuteredge formed ot' two oblique portions, p p. (Sec Figs. Zand 3.) `On' the shaft K acollar, M, is placed loosely, and is-alloweda certain degree of play or movement thereon when a stop, N, is removed. This stop is. constructed similar to a spring. clamp."` It grasps thev shaft K, and is retained vthereon by its o wn elasticity, the stop being `fitted betwcenoneend of the collar M and a should`er,p, on theshaft K. .A conical boss or shell, O, is also placed on the shat'LK to i receive one end ofthe collar M, which at said end is of conical ortaper form and ot increased diametenas shown more particularly at q, Fig.

1 2-,- Thefjcbllar M is encompassed by a loop, r,

(scorge.) The' which is attached to a lever, I?, the lower end guards covering the orifices of conveyin g-tubes S S, the lower ends of Which'areconnected, as shown clearly in Fig. 1. lo the tubes S afurrow-share, l, and 'coveringshare U are attached, as shown clearly in Fig. 1. The two slides Q It are connected by a cross-plate, w,

and to this plate a standard, a", is attached," saidstandard having one end of acurved rod,

WV, attached to it by passing through a slot, b", made therein, so that the rod may rise and fall, the opposite end of the rod resting on the collar'M and bearingagainst the boss or shell O. 4Through the front cross-piere, a* X, of the frame E a vertical spindle, b, passes, and the lower end of this spindle is connected by a link, cx", with a horizontal shaft, alx x, the liearin gs of which are secured to the under side of frame E. To the inner eii'd of the shaft d a vertical rod, ex X, is attached, and a blade or scraper, f x", is. attached to the lower end of the rod ef the blade or scraper penetrating the groundfa suitable depth. A spiral spring, g* x, is placed on the spindle bx", said spring having a tendency to keep th'e blade or scraper fx by the side of the share T.

The operation is as follows: As the machine is drawn along the spur-wheel J rotates. the shaft K through the medium ofthe pinion L, and the shaft K has a longitudinal vibratory movement given it, aswell as arotary one, by means ofthe zigzag slot inthe shaft, in connection with a spring, c", attached to the crossplate fw of the slides F G. The spiral portions n n ofthe zigzag' groove, in consequence of acting against the pin o ot' the tube i, throws the shaft K inward, and when the outer' ends of said portions n of the groove reach the pin o the' shaft K is thrown back to its original position by the spring c", the parts m of the zigzag grooveallowing the shaft to return directly back. In consequence of the double-oblique form of the outer side of the pinion L, said pinion at every semi-revolution passes out' of gear with the wheel Jand the shaft K is allowed toreturn freely back to its original. position without causing any binding of the gearing L J--a contingency likely to occur if provision were not made to prevent it, as the shaft K cannot turn when the pin o is in either of the grooves m. The longitudinal movement of the shaft K gives the reciprocating movement to ,the slides Q It through the medium of the'rod W, which'serves as a latch, and when it is designed to stop the slides Q R the stop `N is withdrawn from'the shaft K and the lever I moved in the direction of the arrow, (sce Fig. 3,) andthe collar M will raise the rod or latch above the enlarged portion g of the collar M. and the spring cX willthrow the end of the latch or rod over the boss or shell O, and the slides will be stopped. The pinion L will also at the same time 'be thrown out of gear with the wheel J, and the necessary longitudinal movement of the 'shaft K ,necessary to eii'ect thisis obtained at any time, irrespective of the position of the zigzag slot and pin o by meanshof the sliding collar i. i v

By means of the rod or latch W, operated as shown, the slides Q R are allowed to be thrown back by the spring c", when the pinion L is ont of gear with wheel J, and the aperture in slide Q will be thrown under the guard n, forming a perfect and quick-acting cut-ofi'.

The slide Q, it will be understood, distributes the corn'or other seed which is planted in hills, and the apertures of the two slides Q R distribute Vtheir seed respectively at opposite sides of the guards u. The slideR will distribute its seed in almost a continuous stream, as the seed is distributed as theshaft K is moved outward from the wheel B', and this movement is slow compared with the ret-urn movement given it by the spring c", and as the seed in' hopper Fis distributed during the quick backward movement of the' shaft K it follows, as a matter of course, that the latter slide will distribute the seed in hills.

The conveying-tubes S and shares T U vmay be raised free from the ground at any time by operating the lever I so that the clutch f may connect the axleA with,f ythe wheel B. The axle will then rotate with the'wheel B', and the eccentrics C C will raise the frame E, onehalf of a revolution of the eccentrics elevating the frame to its highest position. The shoutders c c on the langes b b of the eccentrics serve as stops and arrest the rotation of the eccentrics at each half-revolution and at the two points of adjustment of the frame. The shares may also b'e retained 'at any desired height by varying the position of the eccentrics on the axle A. In commencingr each row the position of thefirst hills planted are designated or marked by depressing the spindle bX by which the blade orscraperf" x is oper ated or thrown outward, so as to vleave a depression ormark distinctly visible to serve as -a guide at the commencement of the succeed ing row, thereby insuring the perfect plant-ing of seed in check-rows.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-'v Y 1. Actnating the seed-slides Q R by means of the shaft K, operated from the wheel B by the spur-wheel J, pinion L, beveled or made of double-oblique form on its outer side, the tube or collar i, provided with the pin o, and the zigzag groove in the shaft K and the spring c", the above parts being arranged to operate as and for the purpose set forth.
